Check Digit Verification of cas no

The CAS Registry Mumber 1187731-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,7,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1187731-52:
(9*1)+(8*1)+(7*8)+(6*7)+(5*7)+(4*3)+(3*1)+(2*5)+(1*2)=177
177 % 10 = 7
So 1187731-52-7 is a valid CAS Registry Number.

Copper-catalyzed asymmetric ring-opening reaction of oxabenzonorbornadienes with Grignard and aluminum reagents

Millet, Renauds,Gremaud, Ludovic,Bernardez, Tania,Palais, Laetitia,Alexakis, Alexandre

experimental part, p. 2101 - 2112 (2009/12/31)

A highly enantioselective method for the copper-catalyzed desymmetrization of oxabenzonorbornadienes with aluminum reagents and SimplePhos as chiral ligand has been developed. The same reaction with Grignard reagents is also reported. A wide range of alky
